Energy Use of Fine Grinding in Mineral Processing
Dec 18, 2013 · Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget.

It is particularly well adapted to the grinding of products at high fineness, very abrasive products and solid fuels, as well as to a wide range of minerals. For large size, Fives has developed the FCB B-mill, using a pioneering technology which consists in supporting the tube mill by tyres integrated into the mill shell, sliding on shoe bearings.
Experiments on phase transformations and chemical
Prolonged grinding increases the energy of solids by the production of stored energy in the form of new surfaces and internal defects. Moreover, grinding also generates quasi-hydrostatic pressures which can result in polymorphic transformations and mineral decomposition. Here we demonstrate the solid-state transformation of metastable to stable polymorphs (aragonite → calcite, anatase ...
